SPEEDOMETER COUPLING Filed April 6. 1940 Patented Feb. 25, 1941 UNITED STATES PATENT QFFICE 1 Claim.

This invention relates to a means for the repair of broken speedometer cables and housings so as to save replacement of the same.

There are approximately 200 different speedometer cables in use on various models of automobiles, and about 150 different speedometer housings. It is therefore. impossible for the average dealer or repair shop proprietor to carry the great number of speedometer cables and 10 housings required for replacement on difierent cars of various years.

Broken speedometer housings and cables are usually replaced, and delay is often caused because the proper housing or cable has to be ordered and shipped from the factory.

It is the object of this invention to provide means whereby a broken speedometer. housing or cable may be repaired within. a very short time so that replacement is not necessary. My 20 invention contemplates a coupling adapted to attach the broken ends of a speedometer housing or cable so that the same may be againused, and

such other objects, advantages and capabalities as will later more fully appear and which are 25 inherently possessed by my invention.

While I have shown in the accompanying drawing a preferred form of my invention, yet I desire it understood that the same is susceptible of modification and change without departing 30 from the spirit of my invention.

Referring to the drawing, Fig. l is a detailed view of a blank from which my'coupling for the housing is formed; Fig. 2 is. a front elevational view of the coupling in place on a repaired hous- 35 ing; Fig. 3 is a view partly in'section of my coupling, as shown in Figs. 1 and 2, in place and Fig. 4 is a sectional view on line 4--4 of Fig. 3.

For the purpose of illustrating my invention let us assume a speedometer housing with portions it! and H, separated by a break. I provide a coupling l2 in the form of a hollow tube, into one open end l3 of which I insert one of the broken ends I!) of the speedometer housing. Into the other open end M of the coupling I2 I 45 insert the other broken end ll of the housing. The ends l and II are inserted so as to meet within the coupling l2.

My coupling I2 may be made of metal or any other suitable material. On either side at substantially half-way between the outer edges and the center of the coupling l2 inwardly extending semi-circular portions l5 are cut through the metal. These portions l5 are bent inwardly on lines E5 to form ears and bear against portions and l l of the speedometer housing to prevent their accidental withdrawal from the coupling l2.

In this repair of the speedometer housing it is 5 not even necessary to remove the housing from the car. The work may all be done by merely joining the loose separated ends as hereto-fore described. The saving of labor and costs will readily be appreciated. There is repair instead 10 of replacement with maximum savings of time and without loss of efficiency of the repaired parts.

My coupling is particularly useful in those instances where the speedometer coupling is not 5 broken, but the speedometer housing is broken because, I form my coupling l2 from a blank 2|, as shown in Fig. 1. The four semi-circular portions l5 are cut through the metal so as to interengage, as shown in Fig. 4, when the coupling is around the joined broken ends [0 and II of the speedometer housing.

Having thus described my invention, I claim:

A construction for repairing a speedometer housing having portions separated by a break comprising a blank, said blank having a pair of spaced out through semi-circular portions adjacent the top portion of the blank and another pair of spaced out through semi-circular portions adjacent the bottom portion of the blank, said blank adapted to be rolled to form a hollow tube with opposite open ends and with the top portion of the blank overlapping the bottom portion so that each of the semi-circular portions of the top portion is positioned directly above a corresponding semi-circular portion on the bottom portion of the blank, one open end of the tube so formed adapted to receive one of the separated portions ti-ons bearing at their ends against the portions of the speedometerhousing to prevent their accidental withdrawal from the tube.
